Dutch researchers had discovered the usefulness of magnetite as an agent in the coal washing process as early as 1912. The coal beneficiation processes is where inorganic impurities are separated from raw mined coal thereby enhancing the combustion characteristic of the coking coal. When finely milled magnetite is suspended in water in cyclones

Washing coal by spiral coal washing plant is an industrial process that separates impurities from raw coal or classifies high-quality coal and inferior coal. The products produced after the coal washing process are generally divided into vermiculite, medium coal, secondary clean coal, and grade A clean coal. By washing coal, coal transportation cost can be reduced and coal utilization can be

The heavy-media separation process, or HMS, employing ferrous media, usually ferrosilicon and/or magnetite, is the most generally used process for sink-float separations. A stable medium over the range of specific gravities from 1.25 to 3.40 can be maintained within close limits and is cleaned and recovered by magnetic means.

The allflux ® procedure uses fluidised bed technology for density sorting and hydraulic classification. This two-stage treatment makes it possible to process a mixture of sand and water without pre-thickening. An upflow that passes through the feed slurry at the coarse sand level causes the light and fine particles to rise up, with the sinking coarse and heavy particles being removed.
